Problems solved by technology

[0004] At present, the types of carbon sources used in research and production are mainly sucrose, cassava flour, molasses, brown sugar and other substances, which not only cost a lot, but also cannot form an effective long-term action system. Therefore, it is necessary to develop a low-cost, It is very necessary to add water quality improvers to carbon sources that can act for a long time, and it is of great significance to promote the healthy development of shrimp farming and reduce the pollution of water bodies caused by farming

Embodiment 1

[0052] A preparation method of a water quality improver for prawn cultivation, the steps are as follows:

[0053] (1) Microbial fermentation: Inoculate the composite Bacillus species in 10 m under aseptic conditions 3 In the microbial fermentation medium of the fermenter, the inoculation amount is 4-5% of the total volume of the medium, at 30-32°C, 180-200r min -1 , continuous aerated fermentation for 90 hours, to obtain a fermented liquid, wherein the microbial fermentation medium includes the following raw materials in parts by weight: 70 parts of straw powder, 20 parts of wheat bran, 3 parts of peptone, 1 part of beef extract, 4 parts of ammonium sulfate, diphosphate 0.5 parts of potassium hydrogen, 0.2 parts of magnesium sulfate;

[0054] (2) Drying: the fermented liquid is filtered through a filter press, concentrated by ultrafiltration, and spray-dried to obtain the bacteria powder of the dried fermented liquid;

[0055] (3) Mixing: add the bacteria powder to the carbo...

Abstract

The invention relates to a water quality improver for prawn cultivation and a preparation method thereof, comprising a carbon source medium and a fermentation liquid of microbial strains, the fermentation liquid of microbial strains is obtained by fermenting microbial strains in a microbial fermentation medium, and the microbial strains Species include Bacillus complex. The invention can form an effective and long-term C / N regulation system; inhibit the reproduction of harmful bacteria, form a large amount of biological flocs, and provide a good environment for the growth of prawns.

Description

technical field [0001] The invention relates to a water quality improver, in particular to a water quality improver for prawn farming and a preparation method thereof. Background technique [0002] With the development of modern industrialization and intensive shrimp farming, the high-density farming model not only makes the ecological system structure of the farming environment single and weak in resistance, but also easily leads to deterioration of water quality and outbreaks of diseases. At the same time, because people often use chemical Drugs and antibiotics are used to prevent and treat prawn diseases. The negative effects of long-term and large-dose use of drugs are also very obvious: it not only changes the normal composition of the intestinal flora of prawns, but also leads to the imbalance of the micro-ecological environment in the intestinal tract. It also makes the drug form residues in the organism, hindering the healthy development of the pollution-free aquacul...
